There have been a lot of instances of Windows could not complete the installation error. People try to install the windows Operating System on their computer but are stuck due to this error. The error statement says that ‘Windows Could Not Complete The Installation. To Install Windows On This Computer, Restart The Installation’. If this error occurs on your computer, then there is an issue with the way you are installing the setup. When the operating system starts up for for the first time, there are two modes in which it can be started. Those modes are the Audit mode and the Welcome mode. The root cause of this error is that you are using the audit mode in order to get the Operating System installed on your machine.

Let us see what the Audit mode actually is

The Audit mode is used to add custom mods to the images of the original windows files. This mode has network enabled. When you boot the Windows Operating System, you will be taken directly to the welcome screen. The welcome screen can be skipped and you can start the audit mode directly. What it does is that the mode allows you to skip to the audit mode i.e. to bring the desktop up immediately after installing and booting.

The error statement  ‘Windows could not complete the installation. To install Windows on this computer, restart the installation.’ will get you stuck in the loop of rebooting and this will stop you in your tracks and make you feel annoyed. We have compiled this guide in order to help you get through all the problems and save you the trouble of jumping from forums to forums in order to find the fix that works for you.
